The QQQ dealer book is long above 730 and moomoo shows it cleanlyLook, MU prints Wed and that's the whole AI-memory tell for the back half of June. QQQ GEX on moomoo right now: flip 730.66, spot 737.58, big positive gamma stack from 738 thru 750, monster call wall at 750. Translation — dealers are long gamma into this print, which usually means slow grind, low realized vol, pin behavior into Wed close. If MU rips and we punch thru 750, that wall flips into a chase. If MU disappoints and we lose 730, the put wall at 725 is the line and below that dealers go short gamma and the tape gets squirrelly fast.The thing I keep telling people about moomoo's GEX feature — it's the same dealer-positioning lens the prop desks pay 4 figures a month for, sitting one tab away from the option chain. Strike-by-strike call vs put gamma, the gamma flip line drawn on the chart, call/put wall labels you don't have to calculate yourself. Updates intraday, not some EOD PDF. On my phone. For zero dollars.If you're trading QQQ weeklies into MU, just check the gamma flip first. Saves you from fading a pin you didn't know was there.
